In today's Remainders: the many. A new multitouch test app shows that multiple fingers confuse the Nexus One; Windows 7 has sold multiple copies (roughly 90 million); Chrome and its numerous extensions are catching up to Firefox, and more

MultiSlouch
Nexus One users have been reporting some multitouch wonkery for a while now, and to get to the bottom of things Robert Green put together the Multitouch Visible Test. The application, available now in the Android Market, basically does what its name suggests, visualizing input by placing colored dots on the screen where it registers your fingers. The first test, on the Droid, runs fine—the dots stick close to the fingers the whole time. On the Nexus One, however, the dots flip around and track to the inverse when the fingers get too close. Google engineer Diana Hackborn responded to the video in a post on the Android developers group:

Shiny
In just the few short months that they have been available for Google Chrome, developers have put together over 3000 extensions for the growing browser. Depending on how you count—Mozilla hasn't released an official number—Chrome has somewhere between one quarter and one half of the extensions as Firefox, which has been racking them up for a considerably longer period.
